The BEST German Chocolate Cake

My entire family loves German Chocolate Cake.  Here's our favorite recipe for it.  I could seriously eat the entire cake by myself, it's SO good!

The BEST German Chocolate Cake

Cake:
Cooking Spray
2 cups flour
1 3/4 cup sugar
1 tsp baking soda
1/4 tsp salt
1 cup butter, cut into small pieces
1 cup water
1/3 cup unsweetened cocoa
2 eggs
1/2 cup buttermilk
1 tsp vanilla

Frosting:
3 egg yolks
1 cup evaporated milk, divided
1 tsp vanilla
1 cup sugar
1/2 cup butter, cut into small pieces
1 1/3 cup flaked, sweetened coconut
1 cup chopped pecans

1.  Preheat oven to 350 degrees.  Spray a 9x13 in baking pan with cooking spray.
2.  To prepare cake, sift flour, sugar, baking soda and salt into a large bowl. (I put it in my Kitchen aid mixer)
3.  In a small saucepan, combine butter, water and cocoa.  Cook over medium heat, stirring occasionally, until butter melts and mixture comes to a simmer.
4.  Add cocoa mixture, eggs, buttermilk and vanilla to flour mixture; stir to combine. Pour into pan and bake 26-30 minutes or until a toothpick inserted in the middle comes out clean.  Cook on wire rack.  Do not remove from pan.
5.  To prepare frosting, whisk egg yolks and about 1/3 cup milk in a saucepan.  Add remaining milk, vanilla and sugar.  Add butter; cook over medium heat, stirring with a wooden spoon, until it comes to a full boil.  Reduce heat to maintain boil and cook, stirring constantly, 7 minutes or until thick.  Remove from heat and stir in coconut and pecans.  Cool, stirring occasionally, until thick enough to spread.
6.  Spread frosting over top of cake.  Serves 16.
